Hello everyone.
At Jagau's request, I am creating a new thread here for permanent magnet motors. Any similarities to other machines can also be discussed here. Don't hold back, every post is important here!
Permanent magnet motors and their similarities.

Hey Atti
I see in this picture the importance you gave to the precision of the location of the magnets on the wheel by drawing a shape on a cardboard.
In the Adams engine it is the precision that is important for success. My biggest problem was the ideal location of the hall sensor, how did you proceed?

Hi Jagau.
As I have already mentioned. This experiment was done years ago. I moved on to another study.But you don't forget these moments. And compare it with other solutions.Notice the variables.
The setting for the question is as follows. As you can see in the drawing. Drawn in red.
You have to push it. (or you have to use an external machine as I have already shown you. Ebm C 720 machine.)
So it can't start by itself.
Then you have to find the right angular position. I would illustrate this in the picture below. (I note here that I agree with the Hall and optocoupler solution you have inserted.)
It is not the high speed that matters,but the filling energy.
In my opinion this should be adjusted to the specific design. So the on and off angle position should be variable within the widest limits. Once this is done, you can choose between the electronic solutions.
(If we think of a solid body. The frequency corresponds to the speed.
The fill factor of the PWM modulator corresponds to the fill factor of the rotor. Of course, the voltage due to the speed must be taken into account.
By the way. Measure the alternator voltage at idle. Rotate the rotor with a drill while observing the fill voltage. This will determine the power generated by the permanent magnet.)
With the experience already gained, I set about building Teruo Kawai's machine.
For other reasons I did not finish it.

Robert Adams says the same thing as you Atti, it is not the speed and a question of torque too, it is also necessary to think that the engine has a kinetic energy that can be counted I believe and this energy can do work. Exemple, Bédini placed a big fan on his engine.
I am working on the phenomenon of resonance on this type of engine which will lower the consumption, very Interesting experiment.
Let us remember what R Adams also said;
The machine, correctly constructed, should still deliver a minmum 107% efficiency.

I hope I'm not derailing the discussion as I haven't had time to read every post here yet... but I was thinking about how you can make what is essentially a "V-Gate" where 2 angled magnets are on the sides and the magnet in the middle which will then go down the track as the magnetic field repels it to.
I was thinking what if that track was curved as much as possible without stopping the effect and run into a loop so the magnet just goes around a long track at a slight curve until reaching the beginning and making its way around again.

Multiply it.Add the generator voltage (and add the ether or whatever you want to call it energy).

I made a short experimental update.I took the engine from the video again.I revived the old experiences.
Unfortunately, I used my older motor for other experiments (it was a mistake).Therefore, I can't do that re-experiment.These were ferrite magnets with a 60 ohm coil resistance.
Later I made a larger version. The neodymium magnet is considered too strong for my realization.(diameter 40mm) The drive stator coils have a resistance of 2x 10 ohm.(diameter 0.3mm) The drive supply voltage is between 12-60V.
At the time I thought that I would drive it with a 12V battery and it would charge a 12V battery. For such a strong magnet this is a low voltage.
So you have to match the drive voltage,the permanent magnet,and the load impedance.
Brief experience.
-No weight on it. So there is no flywheel function.So it slows down abruptly under load.
-The higher the load, the more the rpm drops. Impedance matching is important.
-If the rpm is low, there is no proper filling (no separate alternator coil).
-2x 10 ohm resistors for the drive coils. Should be at least 60-70.
-The load depends on the battery charge,so it is a better choice to use some load resistor instead of battery charging.
